Less than 20 minutes left to go at Selhurst Park and Palace have only had two shots on target at home against the side bottom of the table.

Swansea still lead 1-0 through Alfie Mawson's header and will be moving off the bottom, above Hull City, if it stays like this.

Swansea stalwart Angel Rangel smashes a ball 65 yards up the pitch and then waves his team-mates up. Get out!

Well played Nathan Ake! He charges down an Olivier Giroud effort at the near post and keeps Bournemouth ahead....

Tin hats on as the hosts go down to 10 men. A year and a day ago, Simon Francis was red-carded after 57 minutes at eventual champions Leicester, and Bournemouth managed to hang on for a goalless draw. Can they hold on in their first game of 2017 as they did in their first of 2016?

Backs well and truly to the wall as defender Brad Smith is readied to come on.

Almost a screamer! Ibrahim Afellay strides on to a bouncing ball and catches it as sweetly as you would wish, but his 25-yarder flies just past the post.

Aaron Ramsey runs to the near post - and puts a left-footed volley wide! A total slice.

Four minutes of normal time to go. Plus stoppages. 

Alexis Sanchez stands up a cross from the right and Olivier Giroud is there - and it's nodded away. Brilliant defending.

Can they hang on?

Bournemouth's last 10 minutes will be played out with 10 men after captain Simon Francis is shown a straight red. He comes in on Aaron Ramsey and referee Michael Oliver sends him off.

Is it a red card? I don't really know any more. It was somewhere in the same ball park as Fernandinho and Sofiane Feghouli. It kicks off a bit too as players jostle and push each other.

Francis clearly mouthed that he got the ball. 

What Bournemouth have done well since that second Arsenal goal is keep the ball and eat up the clock.

They do better than that, they play Dan Gosling clean through and everyone almost stops before Gosling curls wide!

The Alexis Sanchez goal was treated very much like a consolation goal by Arsenal's players and supporters alike - but Lucas Perez's second sees the away fans find their voices again, while the men in yellow have a definite spring in their step. There will be more than a few nails bitten among the Bournemouth faithful now as for all their adventurous forward play, they remain defensively frail at times at this level.

Ten minutes to go. But Arsenal scored twice in five.

Joe Ledley has a shot blocked as now it's all Crystal Palace. Are Swansea going to be made to pay for those first-half misses? 

We've had one thrilling comeback at Bournemouth this season - are we on for another?

Bakary Sako is right into the mix, with a stinging shot from a tight angle which Lukasz Fabianski pushes over.

The fans may have been chanting "we want four" but it can be inferred from Eddie Howe's two substitutions - made before the Alexis Sanchez goal - that a touch of steel is needed to see out the game. Defensive midfielder Andrew Surman and full-back Adam Smith, sent on in place of the forward-thinking Joshua King and Ryan Fraser, will reinforce the midfield against an Arsenal onslaught for the last 20 minutes.

Palace have been better since the restart but the next chance comes for the visitors, Gylfi Sigurdsson the conductor of a flowing counter-attack which ends with Jack Cork shooting wide while off balance. 

Speaking of need for inspiration - Arsenal need four goals in 22 minutes. It's not going to happen.

They have been really poor tonight, not a single shot on target so far.
